sort of a followup to ZBX-1344

since the list posted there, situation has slightly improved (down to 64 unused functions from 93 - but that still seems terribly high).
in trunk we have 73 unused functions, excluding tests

some might be correctly unused (like debug functions), but surely not all of them. also, this highlights a few gems in commit messages and change piling - for example, revision 10349 moved several functions from config.inc.php to debug.inc.php. commit message ?
"fixed error when create dependency for trigger that belongs to same template"

functions that were unused then and are unused still in 1.8 svn head :
